Signs It’s Time for Metal Roof Replacement

Home > blog

Even the most durable roofing materials will eventually experience wear-and-tear, and metal roofing products are no exception. While these are some of the longest-lasting roofing materials available on the market today, even they will wear down with enough time – and knowing the signs that this is happening is very important for ensuring repairs or replacements are made at the right time.

At Mid Michigan Metal Sales, we’re here to offer a huge range of metal roofing products for Michigan clients, from metal panels to metal roofing shingles, metal siding and more. Here are some of the telltale signs that it might be time for metal roof replacement, whether we’re talking about certain panels or sections or even your entire roof setup.

Major Rust and Corrosion

In some cases, metal roofing may begin to show signs of rust or corrosion, even if it’s been properly installed and maintained. If you notice this kind of rust forming in significant portions of your roof – particularly on the surface layer – this is a major red flag that it’s time for replacement.

Now, very limited bits of rust or corrosion may not necessarily be an immediate concern, but if you’re seeing it spread or form in multiple areas of your metal roof, it’s worth calling our pros right away. We’ll help you decide whether repairs or replacement are the best route for your specific needs.

Buckling and Warping

Another major sign that metal roofing is coming to its end is when panels or sections are visibly buckling or warping. These issues often start small but can quickly turn into major problems if not properly addressed. Not only does this impact the aesthetic quality of your roof, it may even cause structural concerns that could eventually lead to serious safety risks for those who live in the home.

For instance, buckling or warping can cause gaps and cracks to open between panels, which will allow moisture to seep in for potential water damage. In addition, these issues may create significant draft areas where heat or cool air could escape more easily, leading to major energy bill impacts over time.

Waterproof Coating Wearing Off

Most metal roofs are painted using a waterproof coating that helps prevent damage over time and extends the overall lifespan of the roof. However, this coating will eventually wear away over years of exposure to the elements – particularly harsh climates or heavy precipitation.

In these cases, you may be able to have a new waterproof coating applied as a repair option, but if it’s been worn off entirely in multiple areas, replacement is more likely going to be the best route. Give our pros a call if you’re noticing significant color fading or other signs of waterproof coating wear.

Visible Tears or Other Damage

On the more severe end of things, you might begin to notice visible tears or other forms of damage on metal roofing areas. These could be caused by a variety of potential culprits, from falling debris to serious weather events – but regardless of the cause, they are often signs that replacement is necessary in the near future.

Small tears can often be patched up with simple repairs, but if you’re noticing large or expanding ones, we highly recommend at least consulting with one of our pros to determine the best path forward.

Storm Damage

In a place like Michigan, the most significant form of storm damage to look out for here relates to snow and ice. These are elements that can cause significant damage to metal roofing over time, particularly if they’re left unaddressed for long periods of time. Make sure you’re having any roof issues inspected after major storms or harsh winter weather, just in case.


Have you begun to notice sagging in certain areas of your metal roof? If so, this could be a sign that the structural integrity of your roof has been compromised and needs immediate attention. Again, this is not only a cosmetic issue but also a safety concern for occupants of the home.

Missing Shingles

Finally, if you have metal shingles on your roof, missing shingles are a clear sign that something is wrong. Whether it’s from damage or simply wear-and-tear over time, even a single missing shingle can leave your home vulnerable to water leaks and other issues. Make sure to address this issue as soon as possible to prevent further damage. At Mid Michigan Metal Sales, we’re here to help you with all your metal roofing needs.
